High Level Architecture - RAC 12c Setup Step by Step on Oracle Virtual Box with Oracle Enterprise Linux(OEL)

No comments
RAC setup can be tricky sometimes, In this article and upcoming articles, we are going to discuss the steps to setup up RAC 12c two node in the simple and easy way.

In this article, I will gather the high-level steps that would be required for RAC setup.

High Level Design:














IP's that I would be using:


#Public IP for 2 nodes#
192.168.56.10   racnode1 
192.168.56.11   racnode2 
#Private IP for 2 nodes#   
10.10.0.10      racnode1-priv
10.10.0.11      racnode2-priv
#Virtual IP for 2 nodes# 
192.168.56.111   racnode1-vip
192.168.56.112   racnode2-vip
#SCAN IP # 
192.168.56.121   racdb-scan  
192.168.56.122   racdb-scan  
192.168.56.123   racdb-scan


Steps:

1. Create a DNS server.(Check the post on how to configure it).

2. Create a Virtual Machine Racnode1 

The configuration of RAC Node 1
  • Hard Disk: 60GB
  • Ram: 4 GB
  • OS: Oracle Enterprise Linux 6.4
  • 2 network adapter eth1 and eth2 for Public and Private IP's.
  • Make the IP's Static
  • Install required RPM's or Oracle 12c
  • Create Users and Groups. We will use a separate user for GRID and ORACLE. 

3. Clone Racnode1 to prepare a new machine Racnode2.

The configuration of RAC Node 2.
  • All configuration as racnode1 will be preserved.
  • Change IP address for eth1 and eth2.
  • Change hostname to Racnode2

4. Configure ASM libraries and Disks.

5. Install and Configure Cluster on Racnode1 and it will remotely configure Racnode2.

6. Install Database Oracle Software

7. Create a Database using dbca.
